[ 1/1Inequality]
    Assignment:Find the solution set of inequality x（1+x＾2）＾1/2-x＾2 >-1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         x * ( 1 + x ^ 2 ) ^ 1 / 2 - x ^ 2 > -1         (1)

---

    From inequality(1)：
         x ＞ -0.695621

---

    The final solution set is :
         x ＞ -0.695621
